UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes

Verify the specific suffix 'IJ' against the manufacturer's current datasheet to confirm pinout and package dimensions, as suffixes often denote thermal or mechanical variations. Confirm RoHS compliance status directly from the official documentation before integration. Ensure the QFN-48 footprint matches the design layout precisely. Check for any recent product change notices that might affect availability or specifications.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this component when a design requires four distinct UART ports with substantial buffering capabilities in a compact form factor. The 64-byte FIFOs help mitigate data loss during high-throughput operations. Verify that the 2.25 V to 3.6 V supply range aligns with the system power architecture. Consider the QFN-48 package constraints regarding thermal dissipation and PCB space compared to larger packages like LQFP.

UARTs (Universal Asynchronous Receiver Transmitter) Part Context

This part belongs to the XR16V654 series of quad UART controllers from MaxLinear. It is designed for applications demanding multiple serial interfaces within a single integrated circuit.
